+8262 Please? I want to level up, and I want to improve. Probably of these type? http://web2.0calc.com/questions/urgent-answer-please_3
+8262 $$3x-4y+2+y+8x\\\\=3x-4y+2y+8x\\\\=3x-(4y+2y)+8x\\\\=3-(6y)+8x\\\\=-(3y)+8x\\\\=\fbox{\begin{minipage}{0.8cm}\55xy\vspace{0.1cm}\end{minipage}}$$

+118687 Your LaTex is beautiful but the answer is incorrect. 
3x-4y+2+y+8x
think of the x as a xylophone and the y as a yak
You cannot add xylophones and yaks it just doesn't work!
Lets change the question a little so it makes mores sense.
3x+4y+y+8x
Now you have all these things can you tell me what you have more simply please?
+8262 It is like: A WIZARD OF EARTHSEA
btw, let's do the math!
How much does y equal? If x is by itself, it equals 1. If y is by itself, it equals _______.
what does y equal when it's by itself?
+118687 What?
3x+4y+y+8x
If you have 3 xylophones and 4 yaks, and another xylophone and another 8 yaks
What do you have?
+118687 3x+4y+y+8x
If you have 3 xylophones and 4 yaks, and another xylophone and another 8 yaks
I have xylophones and yaks, you have 21 what exactly?
+118687 Sorry I get you. you have 21 things I guess. No it doesn't work that way.
you have to keep the xylophones and the yaks seperate!
+118687 12yaks and 5 xylophones
a xylophone is the same as 1 xylophone. 
Here is one
6y+9t-y+2y+z (t can be trains if you like)
+118687 that is correct - but you can leave out the times signs.
3t-x+8y-t+2
you cannot add the 2 to the letters - just leave that number alone.
